SL1210 plinth adventure

[6L6]

Beautiful!! It’s going to look so very good.

I think I may do this to mine if I ever get the backlog of projects cleared out…

Can't wait to see the finished TT. That is really beautiful.

Thanks!
Has anybody here experience with armboards for Jelco tonearms? There're some options on eBay:

[peppennino]

Very nice tonearm. Love the V15

 

[peppennino]

Finishing completed. Five layers of Tru Oil. It will dry while waiting for the tonearm and the board...

 

[peppennino]

Armboard for Jelco arrived! 😊



First of all, don't forget a towel!



Inox screws and washers on top side...




...big washers, split washers and nut on down side

 

[peppennino]

Set torque ar 2nM



Done

 

[peppennino]

So... Let's start disassemble the plinth!



Feet and rubber bottom



The heavy resin inner chassis







And the ground on pitch control PCB



My boss whatches me...



At last... The tonearm!



Gently accompanying it to the floor...





Done!



Old tonearm ready for a new adventure

 

[peppennino]

Now from the top...



Plastic cover



Molex connectors








Reg transistor



And motherboard/motor







The spindle



Some mods on start/stop PCB





Removing the strobo and changing the 3mm speed leds



Some cuts occurred

 

[peppennino]

And reassemble it with the veneered chassis!



Resin bottom



MB, motor and cables





No need to screw the rubber bottom for a quick test







Obviously we can remove the towel 😂

 

[peppennino]

As the Pitch Control has been removed, I need to jump Pin 6 and 7 on mother board (Molex CN102), corresponding on red and orange wires on pitch control:





The jumper has the same function of "Zero Click" on slide potentiometer (reset switch S301). You can solder a jumper downside or put a simple PC jumper on molex.

 

[peppennino]

New switch board



New 33/45 switches and new blue LEDs

This is awesome, Peppennino! I am bookmarking this for the future when I am able to do a similar project. Keep up the great work!

 

[peppennino]

Many thanks, Chris 🍻

Little update: 3d printed isolation feet

 

[6L6]

Wow! Those are wonderful!

How do they work?

 

[peppennino]

They're very similar to Isonoe feet
